Ameren testing new technology to boost grid capacity and reliability

ST. LOUIS, Mo., (KBSI) — Ameren is testing new technology designed to increase the capacity and reliability of its existing transmission system as energy demand continues to grow across the Midwest.

The company said it is piloting dynamic line rating (DLR) technology, which provides real-time data on weather conditions and transmission line performance. Officials said the information allows grid operators to safely move electricity more efficiently when and where it is needed.

Ameren is partnering with Heimdall Power to install 30 sensor units on transmission lines, focusing on some of the system’s most congested areas. The sensors collect data on factors such as temperature, wind and sunlight, which affect how much electricity a line can carry.

Company officials said the technology could help increase capacity on existing infrastructure, improve reliability and reduce costs for customers.

The first 15 sensors were installed in December 2025, with the remaining units expected to be deployed later this year. Ameren said future use of the technology will depend on results from the pilot program.

Robert Clausius is the Senior Manager of Transmission Asset and Compliance Management for Ameren he shares that Ameren is currently participating in a pilot program that could benefit both consumers and utility workers.

“When these lines become close to being overloaded, certain generators can’t run at those times and maybe more expensive ones have to run at those times” says Clausius. “So, if we can eliminate those constraints, then the more efficient generators can run more frequently, which then causes the wholesale price of electricity to be lower.”
